Can you restore entire system from a specific date?

    An app I use a lot has started to play up and uninstalling/reinstalling doesn't fix the issue. Therefore I was hoping to restore my mac to a time when it did. However, I can only find info on restoring specific files from past times, or restoring from the last backup. Is there a way I can choose what backup I restore to, or do backups always overwrite the last one? Or is there another way I can restore the whole system from another time?

    Yes. I assume here you are on Lion or better and you did a Time Machine backup to a external drive?

    Option key boot to the TM disk then click restore and you can pick a date from the screen below.

    That's a pretty massive sledgehammer to crack a very small nut.

    I would urge you to try the following first:
    Create a brand new user account, and test the problem there.
    If the app works normally, then it's nothing to do with the OS and system files, but something in your original user account.

    Go back, and try to work out what in your old account might be causing the problem.
    Go to <user/Library/Preferences, and delete the preference files of the app. That's a likely cause.
    Make sure you don't have too many third-party software products running that might conflict or cause trouble.

    Thanks, I 've done this and it doesn't help. However, I have just discovered something that might help explain the issue. I've posted a new thread here

    Thanks, very helpful. Before trying this I'm going to figure out the problem I've just discovered, see link in post above

    OK so my 'problem' appears to be normal. What do you mean by option boot?

    Well I did a restore back to a point my software worked and it didn't fix the issue, so I wiped the hard drive and installed a fresh OS X Mountain Lion but the issue still persisted which has really thrown me :confused:

    Oh well, at least I've learnt how to restore from a previous back up so was still a useful exercise :)

    You should say which app, because the problem might be in a totally different place. For example, the app might rely on a server that is maintained by the maker of the app, and if that server isn't working, then there is nothing the Mac can do about it and all restoring won't make the slightest difference.

    It's Lightroom. I didn't want to go into a lot of detail about the issue as I've already started a thread about that and I didn't want to overlap two threads, see here
